I think if you look in them you will see an error message not an image.

"Unsupported output format (image/geotiff)."

downloading the capabilities file by hand it shows:

<!-- MapServer version 5.0.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=W

      <Format>image/svg+xml</Format>


no geotiff support.  set format= to one of the above.

I tried in a WGS84 lat/lon loc:

g.region n=50:30N s=47:15N w=9E e=13:45E res=0:00:30
r.in.wms mapserver="$SERVER" layer=TK50 out=TK50_Bavaria format=png -g

it seemed to work, but I only got a blank map. Maybe you will have better luck. Using "-g" I got a "(c) Bayerische ..." in the image, without "-g" I didn't. shrug.

maybe you can get something from v.in.wfs?
or try QGIS's or GDAL 1.5+'s WMS import tools?
